最近在用Latex写论文，遇到了一个问题：给通讯作者加特殊字符，如数字或者星号。最后问师姐，才知道了解决方案，下面是加星号的一个例子。

\documentclass[5p,twocolumn,10pt,times]{elsarticle}
\usepackage{amsmath}
\usepackage{hyperref}
%\modulolinenumbers[5]
\addtolength{\textheight}{8mm}
\addtolength{\textwidth}{4mm}
\addtolength{\voffset}{-10mm}
\addtolength{\hoffset}{-3mm}
\usepackage[ruled,vlined]{algorithm2e}
\bibliographystyle{elsarticle-num}
\usepackage{booktabs}
\usepackage{multirow}

\begin{document}
\baselineskip11pt

\begin{frontmatter}

\title{Deep Learning-based Parameterization}
\author{first author}
\author{second author\corref{mycorrespondingauthor}}
\cortext[mycorrespondingauthor]{Corresponding author}
\ead{ttttt@ustc.edu.cn}
\address{School of Mathematical Sciences, University of Science and Technology of China}
%\author{Third Author}
%\address{Department of Computer Science, Tel Aviv University}

在二作second author后面加下面的字符就可以实现加星号：

\corref{mycorrespondingauthor}

下面的效果图：
